Description
Technical field
The utility model relates to a kind of Stretchable locating apparatus of gearbox assembling parts.
Background technique
In assembling, some small parts such as bushing will be pressed into housing bore each part of gearbox, and bushing pressure head is at this time
It is pressed into housing bore, bushing is packed on the positioning pressure head with round section joint ring shape circle first, by the soft of round section joint ring from top to bottom
Property it is fixed without falling down, while also to guarantee that during entire press fitting, bushing is smoothly pressed.But such positioning, bushing meeting
A little crooked, although round section joint ring is flexible, for bushing when just touching shell aperture, bushing can be crooked sometimes, damages shell
Body opening causes shell to be scrapped, and press fitting failure seriously affects installation qualification rate, increases cost.
Summary of the invention
The purpose of this utility model is to provide a kind of Stretchable locating apparatus, overcome former round section joint ring positioning method rapid wear
The low disadvantage of bad shell aperture, press fitting qualification rate.
A kind of Stretchable locating apparatus, it is characterised in that: including two elastic semicircular sleeves, apotting spindle, resilient key, " O " shape
Circle, compressed spring, two elastic semicircular sleeves are located in the outer circle of apotting spindle, and two elastic semicircles are cased with a pin hole, apotting spindle
On be provided with a "u"-shaped groove, with the elastic semicircular sleeve of elastic pin connection two and apotting spindle, resilient key is fixed with round section joint ring, is protected
Card resilient key will not run out, and guarantee that two elastic semicircular sleeves are connect with apotting spindle, between two elastic semicircular sleeves and apotting spindle
A compressed spring has been filled, has guaranteed that two elastic semicircular sleeves are in stretching the state, " U-shaped opened on apotting spindle in non-stress
Slot " guarantees that two elastic semicircular sleeves can be moved up in stress along apotting spindle.
The utility model has the advantages that: the utility model replaces round section joint ring mode to position by Stretchable locating apparatus, from
And realize solid positioning, it is damaged to solve shell aperture during press fitting, the low problem of press fitting qualification rate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the side structure schematic view of Fig. 1；
Fig. 3 is the structural schematic diagram that the utility model clamps bushing；
In figure: two elastic semicircular sleeves 1, apotting spindle 2, resilient key 3, round section joint ring 4, compressed spring 5, bushing 6.
Specific embodiment
The embodiment of the utility model structure is described in detail now in conjunction with attached drawing:
A kind of Stretchable locating apparatus, it is characterised in that: including two elastic semicircular sleeves 1, apotting spindle 2, resilient key 3, " O "
Shape circle 4, compressed spring 5, two elastic semicircular sleeves 1 are located in the outer circle of apotting spindle 2, and two elastic semicircular sleeves 1 have a pin hole,
It is provided with a "u"-shaped groove on apotting spindle, with the elastic semicircular sleeve of the connection of resilient key 3 two and apotting spindle, is fixed with round section joint ring 4
Resilient key 3 guarantees that resilient key 3 will not run out, and guarantees that two elastic semicircular sleeves 1 are connect with apotting spindle 2, two elastic semicircular sleeves
A compressed spring 5 has been filled between 1 and apotting spindle 2, guarantees that two elastic semicircular sleeves 1 are in stretching state in non-stress, it is fixed
" U-lag " opened in the mandrel 2 of position guarantees that two elastic semicircular sleeves 1 can be moved up in stress on apotting spindle 2.It is being pressed
Before, by bushing 6 in 2 bottom end outer circle of apotting spindle, to guarantee stable positioning, protected by the elasticity of two elastic semicircular sleeves 1
Card bushing 6 will not fall down, and when not being pressed, two elastic semicircular sleeves 1 are under the elastic force of compressed spring 5, two elastic semicircular sleeves
1 is in stretching state, always stationary bushing 6, and during press fitting, pressure head is constantly moved down, outside two elastic semicircular sleeves 1
Circle is big compared with housing bore, and with the indentation of bushing 6, two elastic semicircular sleeves 1 overcome the acting in U-lag on slowly of compressed spring 5
It rising, two elastic semicircular sleeves 1 tightly position always bushing 6 during ensure that entire press fitting, it not only ensure that assembling quality in this way, but also
Improve press fitting qualification rate.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, make several equivalent substitute or obvious modifications without departing from the concept of the premise utility, and performance or
Purposes is identical, then shall be regarded as belonging to the protection scope that claims that the utility model is submitted determine.
